1.1 North Korea - 26 May 1952
An F-94 flying a mission was told by ground radar that there was
an unidentified object on its tail. The interceptor aircraft turned
into the unknown and locked on with its radar at 7ooo yds. and started
to close. Both the pilot and the R.O. observed a brilliant white
light straight ahead. The unidentified performed 'a steady climbing
turn and accelerated at a tremendous speed drawing -t away from the F-94

COMMENTS OF PE
From the information obtained it would appear that two objects might have
a relationship to each other, although size or shape of either ene could be
obtained. The point of interest is that the bright light was above our present
bomb line and the unidentified high speed object was to the rear front

An F-94 flying a mission was told by ground radar that there was
an unidentified object on its tail. The interceptor aircraft turned
into the unknown and locked on with its radar at 7ooo yds. and started
to close. Both the pilot and the R.O. observed a brilliant white
light straight ahead. The unidentified performed a steady climbing
turn and accelerated at a tremendous speed drawing away from the F-94
which now had cut in its after-burner. The pilot was unable to close
and the R.0. lost the object a 0 yds. contact.
The airborne radar was checked for malfunction before and after
the mission and found to be in perfect condition... No exhaust patterns
from the unknowm were noticed. Pilot - Lt Radar Oper-
